Haze Control monitoring a brewing process; measuring 7.9 ABS color, showing a trendline of 11° turbidity along with a 90° EBC measurement

Haze Control Converter monitoring both 11° and 90° EBC measurements in a brewery

HC4000 Converter

Superior performance turbidity monitoring converter

Dedicated to optek turbidity sensors the HC4000 provides high precision signal processing combined with flexible configuration of the measurement setup. Several scales, like FTU or EBC can be selected to display the photometric signal in common units with product and process control.

Used For

For NIR/VIS Absorption sensors
Turbidity scales:
- CU (concentration units)
- ppm (DE)
- FTU
- NTU
- FAU
- EBC

The Haze Control 4000 photometric converter is designed to operate with the optek DTF16 (11°/90° scattered light sensor) and additionally with AF16 or AS16, visible (VIS) or near-infrared (NIR) based sensors. The graphic display can show absorbance, turbidity and concentration in real-time and in any unit of measure such as EBC, FTU, ppm (DE), NTU, ASBC and Helms. These measurements may also be displayed as text, bar graphs or trend values. A factory zero point is implemented for the scattered light sensors. A second user defined zero for additional offset is included, as well as a slope and offset adjustment. This manual adjustment can be used to help correlate results to other brands of lab instruments.
